Abstract

Noise is reduced in a circuit that converts voltage. A voltage conversion circuit includes a conversion transistor, a current source transistor, and a control circuit. In this voltage conversion circuit, the conversion transistor converts a potential of an input signal, the potential being changed from one of two different potentials to the other, by using predetermined current, and outputs the converted signal as an output signal. Furthermore, the current source transistor supplies the predetermined current. Then, in a case where the potential of the input signal is changed to the other potential, the control circuit stops supplying the predetermined current.
